language called DDL (Device Description Language) and generate the
Lua

code out of it.
Where I can start with if I dont know how the languages and semantics
works? Are any Lua library supports easy language parsing?
The .NET version (http://irony.codeplex.com/ [1]) is huge and it is
difficult to understand. I believe, Lua could support simple parsing
and AST building and code generation easily.
